"These past couple of weeks have been filled with the most exciting experiences of my life," she wrote in a heart-warming note via Twitter on Wednesday.

The first-time mum said she had been "enjoying this time to fully embrace motherhood and spend time at home with my family."

The reality TV star thanked fans for their "sweet thoughts and best wishes."

"I am so blessed to have the support of my family and fans in this beautiful moment," she continued.

Since having her little one , we have heard very little from the Keeping Up With The Kardashians star, who normally lives her life in the spotlight.

It is clear that she has been bonding with her and Kanye West's daughter.

According to reports, 32-year-old Kim has also been dedicating time to getting her pre-pregnancy figure back.

"Kim looks amazing, she really does," an onlooker said. "She's dropped a lot of the baby weight already. She looked slim and was glowing."

She was spotted in Southern California recently and was said to have kept a low profile by being driven around in an inconspicuous car with a helper.

"As for the baby, Kim and her helper kept a blanket over North's car seat so nobody could catch a glimpse," the source told RadarOnline.com.

Kim has not been seen in public since she welcomed North, known as Nori to her mum and dad Kanye, into the world.

As one of the most photographed people in the world, it 's understandable that she'll want to look her best when she returns to the spotlight.

"She's already looking ahead to when she can exercise again," a source told US Weekly.

"She really wants to get back into shape. It's important to her."

Just before giving birth , Kim hinted at her desire to regain her pre-pregnancy figure, posting a bikini snap on Instagram with the caption, "Can't wait to go back".

During her pregnancy, Kim worked closely with celebrity trainer Tracy Anderson. But she is said to be considering hiring Gunnar Peterson for some extra help. Gunnar is the man behind Khloe Kardashian's recent 25lb weight loss.
